Hard Kr has learned that Shenzhen Polos Technology Co., Ltd. (hereinafter referred to as "Polos") recently completed tens of millions of yuan in Series A financing, which was exclusively strategically invested by Hanlian Semiconductor Industry Fund (hereinafter referred to as "Hanlian Fund"). This round of financing will accelerate Polos' R & D and innovation in intelligent voice enhancement and intelligent voice interaction technologies, and promote the market penetration of its products in more fields.

Polos was founded in 2018. Its R & D team comes from the Chinese Academy of Sciences and industrial institutions, with years of experience in algorithms and integrated circuits. Currently, Polos provides domestic audio chips and solutions with high performance and cost - effectiveness to users through a product system centered on technologies such as audio AI chips with a tri - core heterogeneous architecture of MCU + DSP + NPU, acoustic signal processing algorithms, neural network noise reduction algorithms, and duplex call algorithms. Its products are widely used in various industry intelligent terminals, IPCs, AIPCs, AI toys, portable sound reinforcement devices, intercom devices and other AI hardware, effectively shortening the AI engineering chain and reducing the application threshold and development difficulty of AI technologies.

As an important perception technology, intelligent audio processing is widely used in various intelligent hardware and industry scenarios such as smart home, smart finance, smart cars, smart education, smart medical care, and smart terminals. In the era of large models, voice interaction is deeply integrated with AI and has become one of the most core interaction methods for AI hardware. New - generation intelligent hardware also puts forward higher requirements for SoC processing capabilities, algorithms such as AI noise reduction and voice enhancement, and software - hardware collaborative optimization.

As the front - end acoustic entrance and back - end broadcasting exit of large models, new market opportunities for voice technology are constantly emerging. According to a report by WiseGuyReports, the global market size of intelligent audio SoCs reached 30.4 billion US dollars in 2024 and is expected to soar to 82.6 billion US dollars in 2032. Behind the compound annual growth rate of 13.33% is the ultimate pursuit of SoC processing capabilities, AI noise reduction and voice enhancement algorithms by intelligent hardware.

Wei Xiangcheng, the founder and CEO of Polos, told Hard Kr that the company's core competitiveness lies in: first, the edge intelligence ability of end - side audio processing, which can miniaturize algorithms on a tiny chip while ensuring the restoration degree; second, the integration of traditional acoustic signal processing and neural network noise reduction technologies; third, providing a full - link audio processing solution from the sound pickup end to the playback end.

In addition, "We are now working hard to build a fourth barrier, that is, the ability to combine the end - side and the cloud, to further improve the flexibility and scalability of our products," said Wei Xiangcheng.

Hard Kr has learned that Polos' chip architecture mainly consists of three major parts. In the DSP part, an algorithm framework based on signal processing is built, including modules such as blind source separation, echo cancellation, and audio encoding and decoding; in the NPU part, an algorithm model based on AI chips is built, including acoustic models, language models, and noise reduction models; in the MCU part, the driver and application parts based on algorithms are built to form a complete user solution. Currently, Polos is one of the very few domestic enterprises with full - stack AI audio processing technologies, with a cumulative shipment of 30 million chips.

In 2018, Polos achieved break - even in its first year of establishment. Wei Xiangcheng revealed that the company's revenue and profit have maintained a growth rate of about 50% annually since 2024.

"Next, we will continue to focus on three major categories: AI tools, health, and education," Wei Xiangcheng told Hard Kr. He believes that these fields have great development potential in the future and hopes to develop products that can solve users' actual problems and provide real value, rather than just doing something icing on the cake.

Wei Xiangcheng further said that in the field of AI tool products, the company focuses on products such as IPCs, live - streaming microphones, and recording products, providing audio processing technology support to empower the end - side and the platform side. In the health field, on the one hand, the company is researching and developing dedicated chips for hearing aids for the elderly; on the other hand, based on the concept of "preventing diseases before they occur", it is developing chip products related to sports, which are widely used in cycling and skiing products. In the education field, the company focuses on researching and developing products for children, such as educational and entertainment products, sleep - related peripheral products, as well as intelligent hardware such as learning tablets and dictionary pens.

Wei Xiangcheng said that the company's short - term goals mainly focus on two aspects. One is to rapidly promote the R & D and marketization of hearing aid chip products, so that ordinary people can use products with clear and comfortable sound. The other is to combine hardware with platforms, launch intelligent hardware products based on large models, and quickly introduce them to the market. Wei Xiangcheng said: "We will focus our resources on these two directions to achieve the company's strategic layout and business growth."

Views of the investor:

Hanlian Fund said: We have long - term attention and firm confidence in the broad market space of domestic audio technologies under the wave of large models and new - generation AI hardware. Polos has excellent technical capabilities, innovation capabilities, and market potential. Joining hands with Polos is an important part of Hanlian Industry Fund's layout in the fields of AI and semiconductors. We look forward to the close cooperation between Polos and the enterprises in our ecosystem in the future, jointly promoting the innovation and development of intelligent audio processing and interaction technologies, providing high - quality technical solutions for more industries, and contributing to industrial upgrading.
